COLLAP SIBLE CHAIR Filed June 24, 1968 INVENTOR SHMUEL OLITZKV ATTORNEY United States Patent 3,485,526 COLLAPSIBLE CHAIR Shmuel Olitzky, 3 Simtat Nes Ziona, Tel-Aviv, Israel Filed June 24, 1968, Ser. No. 739,503 Int. Cl. A47c 4/04 US. Cl. 297-31 1 Claim ABSTRACT OF THE DISCLOSURE A collapsible chair is described comprising a back section and a separable seat section, the back section includ ing a pair of spaced side bars secured together at the lower ends by a pair of cross-bars, there being a backrest supported at the upper end of the side bars, a seat section including a pair of side bars, a seat secured thereacross, and a pivotable leg rest, the structure being such that during the use of the chair the cross-bars of the back section support the seat section, and in the collapsed condition of the chair, the leg rest is pivoted to lie between the side bars of the seat section, and the latter section is placed between the side bars of the back section.

BACKGROUND OF THE INVENTION Field of the invention The present invention relates to chairs which may readily be set-up for use and collapsed into a compact form when not in use.

Description of the prior art A wide variety of collapsible chairs have been devised, but as a rule they are costly to produce, or inconvenient to set-up and collapse, or bulky in collapsed form, or uncomfortable to use.

The present invention provides a novel collapsible chair of improved characteristics in each of the above respects.

SUMMARY OF THE PRESENT INVENTION According to the present invention there is provided a collapsible chair comprising a back section and a separable seat section. The back section includes a pair of spaced side bars secured together at the lower end of the section by a pair of cross-bars, and a back rest supported at the upper end of the section. The seat section includes a pair of spaced side bars, a seat secured across the section, and a leg rest pivotably mounted to the section. The spacing of the cross-bars of the back section is greater than the width of the side bars of the seat section enabling the latter section to be inserted between the crossbars and to be supported thereby during use of the chair. To enable the chair to be collapsed in a very simple and compact form, the width of the pivotable leg rest is less than the spacing between the side bars of the seat section enabling the leg rest to be pivoted so as to lie between them, and the spacing of the side bars of the seat section is less than the spacing of the side bars of the back section enabling the seat section to be placed between them.

According to a further feature, the pivotable leg rest includes a pair of rods each pivotably mounted at one end to one side of the leg rest, the opposite end of the rods carrying pins receivable in slots formed on the side bars of the seat section.

The chair may be assembled in a very simple manner by merely inserting the seat section between the crossbars of the back section. For collapsing, the seat section is removed, the leg rest is pivoted so as to be disposed between the side bars of the seat section, and the latter section is placed between the side bars of the back section, thereby providing a very compact collapsed chair. In use the chair including the pivotable leg rest provides 3,485,526 Patented Dec. 23, 1969 a very comfortable support for the user. It will also be seen that the parts are few and simple, and therefore the chair may be constructed very inexpensively.

Additional features and advantages of the invention will be apparent from the further description below.

BRIEF DESCRIPTION OF THE DRAWINGS The invention is herein described, for purposes of example only, with reference to the accompanying drawings, wherein:

FIG. 1 illustrates the chair in assembled condition for use;

FIG. 2 illustrates the seat section including the pivotable leg rest; and

FIG. 3 illustrates the parts in the collapsed condition of the chair.

DESCRIPTION OF THE PREFERRED EMBODIMENT The chair illustrated in the drawings comprises a back section generally designated 2 and a separable seat section generally designated 4.

The back section 2 includes a pair of spaced side bars 6 and 8 secured together at the lower end by a pair of spaced cross-bars 10 and 12, cross-bar 10 extending across one face of the side bars, and cross-bar 12 extending across the other face of the side bars. A further cross-bar 14 is connected across the upper ends of the side bars, and a back-rest 15, such as of canvas, is also secured across the upper end of the side bars.

The seat section 4 includes a pair of spaced side bars 16 and 18. The latter are secured together by a cross-bar 20 at the lower end of the section, and by a plurality of cross-bars or slats 22 at the upper end of the section, the latter bars or slats serving as the seat of the chair.

A leg rest is pivotably mounted at the upper end of the seat section 4, the leg rest including a pair of spaced side bars 24 and 26 and a plurality of cross-bars or slats 28 securing the latter bars together. A pair of rods 30, 32 support the leg rest in the illustrated (FIG. 1) extended position. Each rod is pivotably mounted to one of the side bars 26, 28, the opposite ends of the rods carrying pins 34 (FIG. 2) receivable in slots 36 formed in the side bars 16 and 18 of the seat section 4.

Side bars 6 and 8 of back section 2 are spaced apart a greater distance than the spacing of side bars 16 and 18 of the seat section 4. Also, the spacing of the crossbars 10 and 12 is greater than the width of the side bars 16 and 18 of seat section 4. Thus, to set-up the chair to the using position illustrated in FIG. 1, it is only necessary to pass the side bars 16 and 18 of the seat section 4 between the cross-bars 10 and 12. The lower ends of the side bars in the two sections serve as the legs of the chair. Preferably, these lower ends are cut at a bias, as shown at 38 and 40, to provide a stable support for the chair. Pins 34 at the ends of rods 30 and 32 of the leg rest are inserted into slots 36 of the frame members 16, 18 of the seat section, to support the leg rest for use.

To collapse the chair, it is only necessary to remove the seat section 4 from the back section 2, withdraw the pins 34 of rods 30, 32 from slots 36, pivot the leg rest so that it is disposed between the side bars 16 and 18 of the seat section, and then insert the latter section between cross-bars 10 and 12 with the lower ends 38 pointed downwardly, as shown in FIG. 3. Cross-bars 10, 12 firmly hold the seat section within the back section. The chair thus assumes a very compact collapsed condition which may be easily stored or carried from one place to another. For carrying purposes, the upper crossbar 14 may be provided with a curved recess 14 (FIG. 3) to facilitate holding of the collapsed chair.

Many changes, variations and other applications of the illustrated embodiment may be made.

What is claimed is:

1. A collapsible chair comprising two separable sections; one of said sections constituting the back section of the chair and including a pair of spaced side bars secured together at the lower end thereof by a pair of cross-bars, there being a back-rest supported at the upper end of said side bars; the other of said sections constituting the seat section of the chair and including a pair of spaced side bars, a seat secured thereacross at one end thereof, and a leg rest pivotably mounted to the latter end; the spacing of said cross-bars of the back section being greater than the width of the side bars of the seat section enabling the latter section to be inserted between said cross-bars and to be supported thereby during use of the chair, the width of the pivotable leg rest being less than the spacing between the side bars of the seat section enabling the leg rest to be pivoted so as to lie between same in the collapsed condition of the chair, the spacing of the side bars of the seat section being less than the spacing of the side bars of the back section enabling the seat section to be disposed between the side bars of the back section in the collapsed condition of the chair, said pivotable leg rest including a pair of rods each pivotably mounted at one end thereof to one side of the leg rest, the opposite ends of said rods carrying pins receivable in slots formed on the side bars of the seat section.
